here is what I get :

Current config :

probe http P_HTTP_TEST

interval 5

passdetect interval 2

passdetect count 2

request method get url /test

expect regex trululu

sh probe P_HTTP_TEST detail

probe : P_HTTP_TEST

type : HTTP, state : ACTIVE

for de default tcp port, on the documentation there is a list that says the default tcp port used is 80, if I have a real listening to port 8080, and I try to put the probe either on the serverfarm or the real itself, I see tcp connection on the 80 port instead of the 8080 port. Strange, maybe os bug.

my default tcp probe is :

probe tcp P_TCP_DEFAULT

description probe defaut pour tcp

interval 5

passdetect interval 2

passdetect count 2

thanks for your help.

What is strange is that the http probe when I remove the expect status, the failed reason is still a invalid code and not "User defined Reg-Exp was not found in Host Response"

strange ;-) (I always have strange things with those Lb)

if you only want the regexp to be considered for success or failure, configure an 'expect status 0 999' to permit all status code.

The regexp is only applied after the status matched the expect status.

Regarding your probe, could you show the serverfarm to which you applied the probe and a 'show probe name P_TCP_DEFAULT detail'

Thanks,

Gilles.

here is a sample :

serverfarm : SF_INTRAMUROS_PRD_WWW

real : R_ANUBIS[8082]

do you have any idea why the expect regex doesn't work and return a invalid status code insteand of string not found ? this is quite disturbing.

Thanks,

as I said, you need to configure the expect status.

It is mandatory for the regexp to work.

Also, the response status must be in the range you have configured.

Try to configure an expect status 0 999

G.

Gilles,

I configured both expect status 0 999 and the expect regex trululu.

Now the probe is always successfull, as if the regex was not configured.

I will test with a simpler web service and keep you posted...

thanks for your help.

This seems to be bug related to some version of ACE software as HTTP return code overrides missing regexp. For sure this bug is present in:

system:    Version A2(2.0) [build 3.0(0)A2(2.0)]

Notice the difference between 192.168.1.1 (is missing regex in HTTP response) and 192.168.1.2 (sends regexp in HTTP response). Both are successful and as addition 192.168.1.1 (missing regexp) is showing last status code 200 which seems to be sufficient for probe to pass. 192.168.1.2 (which sends expected regexp) doesn't show last status code.
